Re: [mapguide-users] MySQL connection timing out
I'm having this same issue running MapGuide Server (Version 2.0.2.3011). It looks as though this issue has been resolved (for future a future release ?). I'm new to this community so I don't know how this works, but there is a service ticket for what looks like the same issue... http://trac.osgeo.org/mapguide/ticket/825 What does this mean for me? Do I have to wait for the next release or is there a fix out there somewhere? -Mark George McLean wrote: I left my development server last night thinking things were in pretty good shape but this morning when querying a map no features stored in MySQL and rendered using FDO were displayed.
